Clown's Mustard Plant and Cyclandelate

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Cyclandelate and Clown's Mustard Plant in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Clown's Mustard Plant at all — not against Cyclandelate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Clown's Mustard Plant Itself Has Been Linked To

This is not an interaction — nothing below involves Cyclandelate. It is the side-effect record for Clown's Mustard Plant on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Clown's Mustard Plant, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Clown's Mustard Plant — expand a row for the licensed statement it rests on. We haven’t matched Cyclandelate to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Cyclandelate.

See Every Supplement That Interacts With Cyclandelate

This page covers Clown's Mustard Plant only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cyclandelate page lists 20 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Mistletoe (major), Beer (moderate), Coffee Charcoal (moderate) and European Mandrake (moderate).

By severity: 2 major · 9 moderate · 9 minor.

From our pharmacist’s overview on the Cyclandelate page

“Cyclandelate (Cyclospasmol) works by relaxing and widening blood vessels, and this list warrants real care before you add supplements to it. Two entries stand above the rest: American mistletoe tightens blood vessels and can directly undo what the drug is meant to do, and activated charcoal can soak up the dose in the gut so less reach…”

About Clown's Mustard Plant

What is Clown's Mustard Plant?

  • Indigestion (dyspepsia)
  • Bloating and stomach fullness
  • Irritable bowel syndrome (IBS) symptoms
  • Heartburn and stomach discomfort
  • Gas and cramping

Clown's Mustard Plant (Iberis amara) is a small flowering herb best known as one ingredient in a popular European multi-herb digestive formula used for indigestion and IBS. Most of the supportive evidence comes from studies of that combination product, not the herb by itself, so it is hard to know how well Clown's Mustard alone works. If you want to try it, talk with your pharmacist or doctor first, especially if you are pregnant, breastfeeding, or have ongoing stomach problems.

Iberis amara · Brassicaceae · Whole flowering plant (often used fresh or dried), including seeds · Liquid herbal extract (a key ingredient in multi-herb combination products), tincture
